<test example 2: embodiment 4~8 and comparative example 10~14〉the antibiotic dissolubility test of various anthracene nucleus class anti-malignant tumors
Various anthracene nucleus class anti-malignant tumor antibiotic shown in the table 2 by use level shown in this table, are dissolved among the distilled water for injection 2mL that is combined with nicotiamide 160mg, make each solution and Production Example 1 lyophilization similarly that obtain, make injection (embodiment 4~8).In addition, except mismatching nicotiamide, similarly make injection, make reference substance (comparative example 10~14) with embodiment 4~8.Then, when in each injection that obtains, adding 10% saline and vibrate, in the time of 30 seconds, confirm antibiotic dissolubility.
Its result is as shown in table 2, is not cooperating in anthracene nucleus class anti-malignant tumor antibiotic in the injection of nicotiamide, and antibiotic does not dissolve fully to saline, but in the injection that has cooperated nicotiamide, antibiotic all dissolves at short notice to saline.In addition, the antibiotic name is represented with common name.

<test example 3: embodiment 9~11 and comparative example 15〉dissolubility test in the different injection of nicotiamide use level
As shown in table 3, respectively according to the method same, make the different injection (embodiment 9~11 and comparative example 15) of addition of nicotiamide with Production Example 1.Then, in each injection that obtains, add normal saline 10mL, and the vibration vial, through the time ground confirm antibiotic dissolved state, measure to the consoluet time of antibiotic.
Its result is as shown in table 3, and in not adding the reference substance injection of nicotiamide, dissolving fully to antibiotic need be more than 10 minute, and Halfway Stopping is measured.On the other hand, in the nicotiamide addition was injection more than the 20mg, antibiotic dissolved rapidly.In addition, can confirm that the many more dissolution times of addition of nicotiamide are short more, if addition is that then dissolubility improves rapidly more than the 20mg, dissolving is carried out rapidly.
